REGISTERING SYSTEM.

To all 107mm if may concern.' f

Be it known that I, JOHN W. G'ooDnRHAM, a citizen of the United States, residing at Yonkers, in the county of Westchester, State of New York, have invented certain new and useful Improvements in Registering Systems, of which the following is a full, clear, concise, and exact description.

This invention relates to automatic telephone exchange systems and more particularly to systems employing automatic switches in which such switches are controlled by means of asender located at a central oflice.

It is the object of this invention to provide an improved means for transferring registrations from one register to another.

Itismore specifically the object of this invention to provide an improvement over a system of the type shown rand described in an` application, vSerial No. 568,747, filed June 16, 1922, by E. H. Clark. y

In the system disclosedfn the Clark application, a plurality of multiple contact relays are arranged on a coordinate basis and are energized under the control of a primary registeringy device. They are subsequently utilized in transferring a registration from such primary.. registering device to some other registering device.

feature of the 'present invention an organization of circuits rsuchthat these relays may be commonly available to the primary registers instead of individual thereto.

A further feature of theinvention is the use of an allotter switch to control the effective association of said common relays with a particular primary registering device. f

Other features of the invention result from'the arrangements of the circuits which control the setting of the registers and will be clearly apparent from the detailed description which follows.

The invention has been shown applied lto a full automatic system of the type shown' in Patent No. 1,395,977, issued November' 1, 1921,V to F. A. Stearn and F. J. Scudder. The invention is, however, obviously capable of-a wide rangeV of usage and'is therefore not to be limited to the specific embodiment shown.

In the drawing, the various figures show so.v much ofa telephone exchange system as Application `iled .Tune l12, 1922, Serial No. 567,539.

is necessary to the'understanding of the invention. Fig. 1 shows a calling subscribers substation and switches by means of which a connection may be extended to a called substation, these switches being, diagrammatically indicated, as is a sender selector. The lower portion of Fig. l1 shows a register sender provided with a plurality of step-by-step primary registering devices. Fig. 2 shows transfer relays which are commonly available to a group of senders and other relays also individual to each sender of the group whereby the transfer relays may be controlled. The lower left-hand portion of this figure shows an allotter switch which determines in what order the registrations set upon the senders of its group shall becomeeifective. Fig. 3 shows a set of register relays which may be used to control the selectivo operations of the switches diagrammatically indicated in Fig. 1.

A general description of the system will first be given in order that thedetailed description which follows may be more `vided with'a. plurality of step-by-step primary registering devices. These registering devices may be of any desired character, but are preferably of the type shown and described in Patent No. 1,472,465, issued October 30, 1923, to O. F. Forsberg and R. M. De Vignier. A progression controlling' switch is utilized to direct the successive series of impulses to the proper registering devices. Assuming that the system is to serve a largeexchange area, it may well be that 500 offices `will have to be served. By utilizing the first three registers to record the office designation, one thousand olice ycombinations may be obtained. In the present disclosure, it will be assumed that each ofthe first three registers has only eight cli" ctirc registering poi-ations. thus proiit ing' fora a totalfcapacity-of ll2iotliccs.

All ot the sende-rs ot an exchange ollice are divided into groups. A set ot' inulticontact relays is associated with each group of senders, as is an allotter switch. The multi-contact relays may be ot any desired mechanical construction, but are preiierabty ot the type shown and described in an application, Serial No. 482,106, tiled July -2, 1921, in the naine ot O. F. Forsberg.

lt will be assumed that in order to ,obtain connection to a ccsired office, ,the calling suhsciiber inist dial three tinies, 'ilhree primary stepregistering devices are therefore provi( to receive these series ot inipiilses. register which receives the. first series o impulses will be hereinafter reierred to as the register', the register which receives the second series ot iinpulses vfill be reterrcd to as the B register, and the which receives the third series ot impulses will be referred to as thc i@ register. A set ot eight multi-contact relays is connnonly available to all the C registeiil ot' a particular group ot' senders. Each ot these relays provided with Gillt will be assumed that the C contacts. register has ein'ht e'tl'ectirc positions. dit'icrcnt one or the multi-contact relays, referred to, will be actuated in each ot the ciiiective positions ot an allotted C register.

set ot eight multi-contact relays are coininenl arailablc to all the B registers ot a sentier group, as in the case ot' the C registers. 'lfb/se relays niay be associated vxi h a p rticrer ii re is er under the control oi? :in adotter. rlhese multi-contact re- :ave eight contacts thus provida resaltot the eight posthe l register and the i "L setti oit the register. A n it these eight relays is operrzi'efiiiic position ot a` l regihns be ebrious that by snitfting the El. l and C registers 7s to which such registers potential inay be dioctlets. Eightoutn the fr register are niultipled to en r ivires et the eight res. h the B register and, in with which one ot the relays associ; en with the register is energized,

any one ot Si? outlets may be supplied with fvl Il ll Olli? (1i potential. aesc tri; outlets are multipled io e eight Vrehrys associated with the 'C re iste vaine ,in accordance ivith which one oit these relays is energized, potential may be supplied toi-any one vot '512 outlets.

There vis Aassociateil with achgroup et senders, a niulti-contact relay organization comprising i312 relays, each having twenty contacts. viht'ter the `prin'iary step-loy-step registers have been positioned, potential is siipplied-to the desired outlet selected by the primary registers of the sender under the control ot an allotter which prevents interterence between senders ot the saine group. (lne ot the 512 control relays is thereupon energized and places the proper combination otpotentials on the cross ivires ot the transter relay traine.

vrllherc 'is iproif'id'ed tor each sender a relay haring twenty contacts a portion only c? `which are shown. VFlach ofthese relays has access to the coinnion innltiple cross lires which have been provided with a suitable combination ot potentials under the control ot the registers. lUpon the energization ot ,the multicontact relay -Which is individual to a particular sender, the desired combination ol potentials is placed on nineteen conductors extending to the register relaj.s ot 3,-Wliich are individual to the corresponding sender. rEhese relays, pon energization, are locked up and are hen utilized to control the selective Voperations ot the switches which establish the connection in a Well-known manner.

Snirnning np, the organization -is such that by means ot a set'ot-prirnary registerinfr devices,comprising A, l?) and C registers and `the connnon relays which cooperate with an allotted register set, one ot 512 reays which are connnongto the senders et a groep is energized'under the control ot the allotter. The particular oneo't 512 relays energized places potentialon the particular ones ofthe cross Wires which Will accomplish the energization ot the Adesired ones of the register' relays ot Fig. 3. litter the regisation isplaced on the con'nnon cross VWires the transfer relay structure, 'the registration is .directed to the register `relays el the particular saider then allotted by ineans ot" a relay individual-to such sender. lt is obvious ,that by combinations ot the nineteen register 1 ot lztig. 3, inorelthan 512 o-tlice designat ns inay be recorded so that it `will not he necessary to use allpossiblc conil'iinations ot the register relays. it is also obvious that by changingthe coinbination ot potentials controlled by any one of the 512 relays which 'functionlin connection .with the transfer traine that the change in renting thus accoinplislied'will be automatically ctteetiye on all the senders ot al groep. it the terminals ot the correspond ing register relays of all register relays oi' all groups are inultipledand brought to a distributing ytraine, it is obvious-,that a change ot' renting inay be accomplished by simply changing connec ions atsuch distributing traine, and that such vchange will then 'be effective on all the senders otthe exchange. The advantage in the Way of coininon cross connections -which is incident 'to the use et a translator switch vis thus retained in the impulses.

naergea'i senderto be lassociated with the trunk circuit which has bsentalen for use. The operation oft the line switch'Q, and the sender selector' 3 are Well known, and` itis believed that their operation will be understood' without further description. The previously mentioned Patent No. 1,395,977, shows suitable circuits for laccomplishing this operation.

It will beV assumed that the register sender shown in Figs. 1, 2 and 3 is 'associated with the calling ysubscribers line. As soon as such association is completed, line Arelay-4C is energized over t-he line loo-p of the calling substation'by Way of the wipers andV contacts of' the sender selector ..3 and line f-switeh Q. The energization ofline relay l causes the enen'gization-oi slow release relay 5. The energization of relay causes the energization of stepping magnet 6 of the control switch over a circuit extending' byy way'ofthe right hand armature'and back .contact ot slow release relay'7 andthe right 'hand and withdraws the stepping paWl-into engagement with new tooth of the-ratchet so that .upon deenergization, .the control sv-.v'itch may advanced'.

The calling subscriber now-:operates his sisbstal ion dial to transmit ytlielirst' series of The first deencrgization. of line relay 4 c'auses'thefenergization of slow release relay 7 which. upon energization causes the deenergi'zation of. magnet 6 so lthat/the control switch advancesits wipers into engagement with' theirirst contactss. A circuit is then completedj fronrgrounded battery, stepping magnet 8, which controls the A register switch, wiper' 9 and its irstcontact', left handarmature and frontcontactof'relay 5, armature and back Contact of relay l t,r to ground. Magnet 8 is energized but does not advance the Av register until relay.` t is again-energized upon the'completion of the irst impulse. Relays 5 and`7. being slow to release remain energized duringl the sending of the first series of impulses. 'When theseries of impulses is completed, vthe continuedenergization of relay 1- for a relatively long period causes the deenergivzation ot relay 7.Y Control. switch magnet is again energized soythatf upon the start of thesend- 'shown in the The B register is rpositioned in the well.

Upon the start of the third linownmanner. series of in'lpulses the control suf'itclrplaces stepping' magnet 11 of the C registerfunder the control oil the line relay 4l. After this series of impulses has been transmittedv the vsubscriber sends the digits o't'thev wanted number. Since the present invention is not concerned'with the method of recording this registration, it will be assumed that they are received in a manner corresponding to that Y previously mentioned Patent No. .L-395,977."l

As soon as the C register is completely positioned,Y as is vindicated by thefdeenergization ot'slbw releaserelay 7, a circuit is completed from grounded battery, winding ofrstart relay 112, armature andbacljcontact of relay v13,"righthand armature and back AContact olf relay 7 ,Y C'register brush '14 and some off normal contact' to ground. Relay 12 is energized in.

'Magnet 17 interrupts its own cirycuit to cause the advance vof the allotter 4'switch into engagement witlrterminalsasvsigned to the particular sender on which .the v'fstait lrelay is actuated.l 'lVhen the wipers ot the allotter switchengage such terminals, a

circuit isV completed.y from. grounded: battery, winding'of test'relay 16,1"allotter'brush 7S a'ndf its` second contact,`which itf'will be assumed--is the contact-'assigned to the-sender shown in' Fig. Y1, :conductor '19,fzmiddle annafture and front contact'of `1'elay"12,to ground.

Testv relay 16 i-s venergized .and kopens the cir-v Yergiz'ation of stepping magnet 17 allows slow r release magnet 18 todeenergize and complete a. circnitfrom ground, through its i armature and back contact-,fright hand ar- Infat'ureand Jfront contact of relay 16,*allotter brushffQO and its second" contact, conductor 21, winding of relay 22, to grounded battery. .Relay 22 is energized, and` at its left hand .andfthefC register Vin position 2. The enerfgifzation of: relayf 22, therefore, completesy `a circuit from grounded battery, winding of relay 23, .outer .right hand armature and front contactiof relay 22, A register brush 24, and its gthird contact, conductorv25, and ltlienceto the grid .Wiire26 of the relay structureassociated-With the 'B register. At the same time, a `circuit is Acompleted `from grounded battery, Winding' of relay 23, iniddle right hand armature fand front contact offrelay 2 2, -B register brush 27 and its second f contact, conductor 28, Winding of relay magnet 29, ;to ground. vMagnet 29 is energized and extends :battery supply from grid Wire26 toiconduc-tor 30. "It isito-be un- .,derstood 4that there are eight grid Wires common to the eight relays corresponding to relay 29. For the sake of simplifying the disclosure theyfhavefgnot all been shown.

The energization :di Arelay 22 :also 'completes a circuit from grounded battery, Winding Vo-relay- 23, innerright fhand armature and front contact of relay 22,C1register `brush 31 and its1second contact, conclue- `tor .32; -Winding of rel-ay magnet 33, to ground. Relay 33 is energized and connects its contactsito the common grid-Wires :which yare :associated .with the lB register irelays. 'It is to 'be understood that there .-.are 64 o -athese ycommon grid wires, -a porltion only .of these .Wires 'being shown to .avoid lneedless extension .of the drawings. `The .energization (if :relay 33 lextends 'con- .'ductor 30 :to conductor -35 by Way of grid `Wire 36. The battery potential supplied to fconcl-uctor 351causes rthefenergization of relay magnet 37, .which kis energized, `and supplesbattery :potentialto desired ones of the cross 4,Wires lWhich constitute the grid of fthe-transfer relaystructure. :It is obvious thatot-he relay --magnetf37 has been selected .out offthe1-512 .siinilarzniagnetsasa result of the coordination of the A, ,IB ,and t() registers and the multi-contact relaysavhich have -been associated lwith them. YIt is also obavionsl that -no i other relays .corresponding to 3,7 can be energized at this timesince they can fonly belenergized under thecontrol of a relay .corresponding `to -relay 22. Since Arelay 22 isk energized underthe controlof an Aallot-ter, it .is yobvious 'that even though 'the sendersvvhich are indicated by the dotted y .rectangles tofthe left off '.Figs. 1 and 2 have itheir registers positioned, such positioning Ais Without :effect 4on lthe: 'transfer structure sincezthe allotter can assign onlyonesender at aitime. Furthermore, the fact that the registers :associated With othersenders may be positioned, can have no eect on the groups of relays containing'relays 29 and '.33 .since the'energization of these relays is controlled by relay-22 and the'relay 22 ot (onlycne sender can tbe :energized at a time ,sinceit-.is'underthe direct control ofthe al- -lotter 'It should'be 'noted-that the conductorsti25, A 28,.32,fetc., are `indicated as being multipled lto `corresponding Vpoints on .the registers associated with othersenders inthe saine allottergroup.

It is to be observed that the circuitsjust described, which Were completed through the .Winding of relay 23, Acause the energizationiof this relay. '.llhe energization of relay'23 c auses'the energization-otl relay magnet 38 over an obvious circuit. Relay 38 is individual to the sender under allotment and ;tlie.e1iergization of 'this relay causes the registration set up on the grid Wires'to be transferred to the register relays of Fig. 3.

-It is .believed thatthe method of trans- :ferring the registration to 'the lregister relays o-f gFig. 3 ,Will readily be understood. The energization of relay -Inagnet '137 .places .battery potenti-alon thecommon grid .Wires 39,140, 41,312, 43,44 and .45,Eindicative of the dialed oiiice code No. 322, and the energizationrof relay magnet 38, '.Which'is individual Ato .fthe fparticular sender under allotment,

causes :this ,battery potential .to be supplied ,tov conductors .146, 47, :48, 49, 50, 51 Vand 52, respectively. df ,--any vother relay had been .operated,sayf80, battery Wou'ldbe supplied togrid ,Wires 40, 62, `63 and 64 andtransiferredto.conductors 47,=65, 66 and 27. Relay 80, 1t .Will benoted, iWill be'energized in .response ito the :registration of No. 422. 'For eachfnum'ber registered a different relay of the'37 group .Willibe'operated and battery [potential vvillbe supplied to the proper conductors in Araccord-ance therewith. It is to fbe-.understood :that each of the conductors .inumbered from 461to 52,'1nclusive, is perma- -nently connectedsto the right-hand Winding .of 'one .of the :register relays of Lliig. 3.

YThere are -as many of these conductors as` there are register relays in Fig. 3. All of the conductors'have-not been shown in order rto -avoid needless duplication. The actual -connection v-from"theconductors to the relays is snot shown, since it is believed that thelarra-ngement offthis part of the system may rreadily beT understood wvithout showing the actual conductors. The conductors have been shown as terminating in the cable .which is :tanned out'ito thervarious rows of relays atpoints 54,55, 56, 57 and 58. `N ineteenv register relayshave been shown in Fig. 3 yand it -vvillltherefore be assumed that 19 conductors extend tothe contacts of V`relay 33 andthat these 19contacts are selectively supplied With potentialby means of the 19 grid Wires'corresponding to Wires 39 to 45, inclusive, Which .are in turn selectively sup plied With potential iin accordance With which oneof the relays corresponding to re- -lay 37 is energized. By selectively supply- `ing potential to theset-ot l19 conductors of Whichconductors 46 to 52 are a part, the 19 register -relays of Fig. 3 aree-selectively ener- -gizedfby means of a Circuit 1from batteryto -J on ground through their right-hand windings. Thesedrelays, upon 'energisation,` lock" up through their left-hand windings. The locking battery supply is not shown, but it is supplied in the saine manner as it is supplied inthe previously mentioned Patent NQ. 1,395,977. the register relays of Fig. 3 correspond exactly and bear the same numerical designationI as the register relays of Fig. 10 ot' the patent just mentioned.v The controlling leads by means of which these relays control the selective operations of the district and oiice switches and also by means of which they control the determination of the class of call, are identical with those shown in the above patent. It is, therefore, believed that no further description is needed as to the method in whichl these register relays control counting relays to govern the switches indicated in Fig. 1, since a complete description of an identical operation occurs in the patent.

While this registration is being transferred to the relays of Fig. 3, the calling subscriber has been sending in series ofimpulses in accordance with the numerical designation of the wanted line. These impulses are received on registers as `described in the mentioned Patent No. 1,395,977, and are later utilized to control incoming and iinal selector switches or else to control a `call indicator at an operators position.

Since this part of the operation of the system is in every way similar to that shown and described in such patent, it is believed that description of this part of the operation is unnecessary in the present application.

1t should be observed that the energization of relay magnet 38 selectively supplies battery simultaneously to the relays of Fig. 3 and that no more time is required for this transfer than would be required for the energization of a single relay.

rlhe energization of relay magnet 38, which causes the transfer ot' the registrations rom the relays of Fig. 2 to those of Fig. 3, also causes the immediate advance of the allotter switch. The advance of the allotter switch is accomplished due to the completion of a circuit from ground, the upper cross wire of the grid served by the relays corresponding to relay 38, the inner contact of relay 38, conductor 59, allotter brush 60 and its second contact, ai'mature and back contact and winding` of allotter stepping magnet 17 to grounded battery. The allotter switch advances itsl wipers one step thus causing the release of relays 22 and 12. The circuit of relay 22 is opened by allotter brush 61. rlhe release of relay 22 causes the deenergization ot' relay 213 which allows relay magnet 38 to be deenergized. Deenergization of relay 22 also It should be observed thatA causes the release of relay magnets 29 and 83 vas well as relay'magne't 37.

It should be noted that relay 22, upon eneijgization, causes the energization ot relay 13 which is locked up to ground at an oiiinormal contact served by C registerbrush 14.

The energization ot' relay 13 holds openthe originalenergizing circuitl Vot relay 12 to prevent the reenergization or continued energization of relay 12 and thus prevents the allotter from allotting the saine sender.

After the allotterhas advanced one step it remains in this position until some other sender is to beallotted. 1f there has been a sender waiting allotment the energization of the relay corresponding to relay 12 at such sender supplies ground to the multiple starting conductor 15 which causes the advance of the allotter in a manner identical'withv that lirst described. Such a circuit can be completed as soon as relay 12 is deenergized upon the advance of the allotter, since such advance allows test relay 16 to be deenergized. y i

rthe sender is released in a manner substantially identical with that described in Patent No. 1,395,977. rlhe continued deen-Y ergization of line relay 4 causes the deenerrgization of slow release relay 5 which causes the successive completion of self-'interrupting circuits for magnets G, 8, 10 and 11 of the control switch and the 14,13, C registers respectively in av manner so obvious and well-known as not to need description. When the C register reaches its normal position register brush 14 opens the holding circuit of relay 13 and this relay is deenergized. The register relays of Fig. 3 are deenergized as soon as tlie battery supply is removed trom the conductors to which said relays are locked through their riglit-liand windings. Tlie release of these relays is accomplished in a manner identical with that described in Patent No. 1,895,977.

All parts oit the apparatus have now been restored to their normal condition and are ready for reuse.
